Geotechnical Mining

Surface Excavation Modelling

RTA has the expertise in modelling many different types of excavations, including fully coupled saturated fluid flow problems. We have the ability to model surface excavations at many scales.

Underground Excavation Modelling

RTA’s geotechnical staff has the expertise in finite element modelling of underground excavation and mining applications such as block caving and long wall applications. We can quickly adapt models to investigate a wide range of input parameters and rock properties to suit any given problem.
